Founded in 2000, our name comes from Scotland’s Isle of Tiree (pronounced Tie-ree), a rugged island that stands strong against the winds and waves of the North Atlantic. Strong and determined. Just like us.
We’re a team of 300+ accomplished professionals in real property, project management, security, and technology, dedicated to applying our expertise to solve critical challenges for our clients.
Headquartered in Ottawa, we’ve helped shape the landscape across Canada and abroad. Over the past 25 years, we’ve had the immense privilege of contributing to some of the largest and most complex infrastructure projects—a role that we do not take for granted.
The scale of these projects reflects the strength of the team behind them. People join Tiree to collaborate, create, and contribute. To be heard and respected. To build lasting relationships, and to grow their careers alongside the industry’s best.
We’re proud of our legacy—and even more proud of the people who make it possible.
